Their plan calls for a large nature bridge to be built over a highway to create a new park, garden space, pathways and a pedestrian connection between the city, the mountains and the river.

The area is one of the main entrances to the city by car and large highway fragments fabric, dividing neighborhoods and green pockets.

The bridge would cross over the highway and maintain the important transportation corridor for cars and trains.

Their proposal calls for a land bridge that creates a nature connection between the surrounding green spaces, the river, La Trinitat and the city to the south.

The space is neither wild nor an manicured urban park, but rather domesticated nature, where one can find community vegetable gardens, open air green spaces, paths, wildflowers and lots of trees.
